Carpanthea pomeridiana is the only type of monotypic genus Carpanthea from the family of aizoaceae (Aizoaceae). The botanical name of the genus is derived from the Greek words carpos for 'fruit' and anthos for 'blossom' and probably refers to the open fruits of the species, which look like a star-shaped blossom when opened.
